Catalogue Note

The present lot, reference 5513, was introduced in 1962.  Widely considered the pinnacle reference in the Rolex Submariner lineage, this example has been marked with an 'underline' to the dial.

It has been theorised that this underline, a very interesting and unusual feature, denotes the transition period between the use of radium luminescence and tritium luminescence. Indeed, measurements have been taken showing that these 'underline' dials emit lesser levels of radiation suggesting the presence of Tritium over Radium.
